Application March 31, 1937, Serial No. 134,081

' pp g.

The primary object of the present invention is to provide a new and improved article of manufacture comprising a non-slip sandal which may be worn to prevent slipping in bath tubs and other slippery places.

Another object is to provide a new and improved non-slip sandal of the character set forth and having flexible and resilient securing straps formed integrally therewith so that the entire article may be molded in one piece to provide an economic construction.

I accomplish these and other objects by means of the improved device disclosed in the drawing forming a part of the present application, and

Fig. 1 is a bottom plan view of my improved sandal; r

Fig. 2 is a side elevation thereof; and

Fig. 3 is a transverse sectional view.

Referring to the drawing:

The numeral I is used to designate a flat sole of flexible and resilient material such as rubber or the like, and having a plurality of resilient suction cups 2 and also having generally longitudinally disposed ribs] formed integrally with said sole and extending from the bottom thereof, as disclosed in Figs. 1 and 2 of the drawing.

The ribs 3 are preferably extended beyond the cups 2 in order that a portion of the weight of the wearer will be borne by said ribs independq ently of the cups and thereby prevent flattening of said cups and consequent destruction of their suction properties.

In order that the sandal may be easily and emciently applied and held upon the foot of a wearer I- have provided the integrally formed straps 4 for embracing the foot and joined, if desired, by

a connecting strap 5, as disclosed in Fig. 2 of the drawing. These straps 4 and 5 are also formed integrally with the sole I and, therefore, are of the same flexible and resilient material so that they may be stretched slightly to securely embrace feet of different sizes, within certain limits.

In operation, the weight of a wearer will flatten sufficiently the ribs 3 to permit. the suction cups 2 to engage and hold to a supporting surface and thereby prevent slipping of said sandal on said surface while the flexible straps 4 will tend to hold the foot of a wearer to the sandal.

By forming the structure, including the cups 2, ribs 3 and straps 4 and 5 integrally with the fiat resilient sole I, anew and useful article of manufacture may be easily and economically prowith a plurality of suction cups and supportingribs between said cups and extending from and formed integrally with the bottom of said sole,

said ribs extending beyond said cups to relieve the same of a portion of the weight of a wearer; and flexible means for "securing said sandal to the foot of a wearer.

3 3. In a new article of manufacture, a non-slip sandal comprising a flat resilient sole provided with a plurality of suction cups and supporting ribs extending substantially longitudinally of said sole and between said cups and also extending from and formed integrally with the bottom of said sole, said ribs extendingbeyond the ends of said cups to relieve the. same of a portion of the weight of a wearer; and flexible straps formed integrally with said sole for yieldingly embracing the foot of a wearer.
